Abstract

Cette invention concerne des techniques pour réaliser une commande de gain automatique (AGC) sur un récepteur sans fil. Le gain total pour le récepteur sans fil est obtenu par des paliers de gain discrets pour un circuit analogique et par un gain continu pour un amplificateur à gain variable numérique (DVGA). Une boucle AGC est actualisée sur la base des mesures de puissance pour un signal de sortie provenant de l'amplificateur DVGA. Un premier gain pour le circuit analogique est sélectionné parmi les multiples valeurs de gain discrètes sur la base de la boucle AGC, pour maintenir la puissance moyenne d'un signal de bande de base à l'intérieur d'une plage prédéterminée à l'entrée d'un convertisseur analogique/numérique (ADC). Un second gain pour l'amplificateur DVGA est sélectionné sur la base de la boucle AGC, pour maintenir la puissance moyenne du signal de sortie à un niveau de puissance de référence. Le premier gain est commuté de façon à éviter la saturation du convertisseur ADC causée par le signal de bande de base et de façon à produire une hystérésis de commutation. La commande AGC peut être exécutée dans le domaine logarithmique et avec des modes multiples.
